Description

この発明は、空気調和機の故障診断システム、詳しくは、空気調和機又はそれと同類の設備機器の故障診断を行う空気調和機の故障診断システムに関する。   The present invention relates to an air conditioner failure diagnosis system, and more particularly, to an air conditioner failure diagnosis system that performs failure diagnosis of an air conditioner or similar equipment.

従来、複数の空気調和機とデータ伝送路を介して接続され、各空気調和機の運転を制御するとともにそれらの運転状態を監視する、少なくとも１つの、例えば、マイクロプロセッサを用いて構成される設備監視装置により、故障が発生した空気調和機から得られた故障情報に基づき予め想定される諸事項について故障診断する故障診断装置が知られている（特許文献１を参照）。
また、上記設備監視装置と同様の監視装置とインターネット等の公衆通信回線を介して接続される監視用端末により空気調和機の故障発生が検知された際、該空気調和機の故障診断を行うようにした遠隔故障診断装置が知られている（特許文献２を参照）。 Conventionally, equipment that is connected to a plurality of air conditioners via a data transmission path, controls the operation of each air conditioner, and monitors their operating state, for example, using a microprocessor. 2. Description of the Related Art A failure diagnosis device that performs failure diagnosis on various matters that are assumed in advance based on failure information obtained from an air conditioner in which a failure has occurred is known (see Patent Document 1).
In addition, when a failure of the air conditioner is detected by a monitoring terminal connected to the monitoring device similar to the facility monitoring device via a public communication line such as the Internet, a failure diagnosis of the air conditioner is performed. A remote fault diagnosis device is known (see Patent Document 2).

しかし、上記従来形式の故障診断装置においては、故障診断プログラムは臨機応変に変更することができず、故障診断範囲が限定されたものであるばかりか、空気調和機の故障診断プログラムに実装された予め想定される故障事象と一致しない場合、該故障事象に対応することができず、正確な故障診断ができないという問題があった。 However, in the above-described conventional failure diagnosis apparatus, the failure diagnosis program cannot be changed in a flexible manner, and the failure diagnosis range is limited, and is implemented in the failure diagnosis program of the air conditioner. When the failure event does not coincide with the failure event assumed in advance, the failure event cannot be dealt with, and there is a problem that an accurate failure diagnosis cannot be performed.

また、インターネットを介して故障診断する遠隔故障診断装置においては、セキュリティの面から、パスワードによりアクセス制限をかけるか又は専用回線を使用することにより対処しているが、緊急性の高い故障が発生したとき、迅速に対応することができないという問題があった。   Moreover, in the remote failure diagnosis device that diagnoses failures via the Internet, from the security point of view, it is dealt with by restricting access with a password or using a dedicated line, but a highly urgent failure has occurred. There was a problem that it was not possible to respond quickly.

さらに、故障診断機能を具備しない空気調和機又は空調監視装置においては、故障診断に必要な故障状態情報が得られず、遠隔故障診断ができないという問題があった。
特開２００４−９２９７６号公報 特開平１１−２３０６０２号公報 Further, in an air conditioner or an air conditioning monitoring device that does not have a failure diagnosis function, there is a problem that failure state information necessary for failure diagnosis cannot be obtained and remote failure diagnosis cannot be performed.

この発明の空気調和機の故障診断システムは、設備監視装置に空気調和機の故障診断用のプログラムをメールデータとして受信するメール受信手段と受信した故障診断プログラムの実行手段とを設け、監視用端末が上記設備監視装置から通信回線を介して空気調和機の故障発生を検知した際、該監視用端末から上記設備監視装置に送信したメールデータに基づき上記空気調和機の故障診断を実行するように構成したことを特徴とするものである。   The failure diagnosis system for an air conditioner according to the present invention is provided with a mail receiving means for receiving a failure diagnosis program for an air conditioner as mail data and an execution means for the received failure diagnosis program in the equipment monitoring device, and a monitoring terminal When the occurrence of failure of the air conditioner is detected from the facility monitoring device via the communication line, the failure diagnosis of the air conditioner is executed based on the mail data transmitted from the monitoring terminal to the facility monitoring device. It is characterized by comprising.

本発明の空気調和機の故障診断システムは、実行する故障診断プログラムをメールデータとして受信するよう構成したので、設備監視装置の記憶手段に、予め多大な故障診断プログラムを記憶する必要がなく、非常に低コストで簡単な設備によって空気調和機の制御及び監視が可能であるとともに、必要時に迅速かつ的確に必要な故障診断プログラムを取得して容易に故障診断及び対応処置を行うことができるという優れた効果を奏し得る。   Since the failure diagnosis system for an air conditioner according to the present invention is configured to receive a failure diagnosis program to be executed as mail data, it is not necessary to store a large number of failure diagnosis programs in advance in the storage means of the equipment monitoring device. In addition, it is possible to control and monitor the air conditioner with low-cost and simple equipment, and to acquire the necessary failure diagnosis program quickly and accurately when necessary, and easily perform failure diagnosis and countermeasures. The effects can be achieved.

Each user management terminal device 6 monitors the operation control and operation state of each air conditioner managed by the facility monitoring apparatus 1 using browsing software (such as a WWW browser).

ＬＡＮ５は、例えば、ダイアルアップルータ７を介してインターネット等の公衆通信回線８と双方向通信可能に接続される。公衆通信回線８には、後述する管理センター１４内に配置された監視用端末装置９がダイアルアップルータ１２を介して双方向通信可能に接続される。   For example, the LAN 5 is connected to a public communication line 8 such as the Internet via a dial-up router 7 so as to be capable of bidirectional communication. A monitoring terminal device 9 arranged in a management center 14 to be described later is connected to the public communication line 8 via a dial-up router 12 so as to be capable of bidirectional communication.

各設備監視装置１から適宜に離間した遠隔地に管理センター１４が配置される。管理センター１４には、公衆通信回線８にダイアルアップルータ１２を介して接続したデータ伝送線に、例えば、パソコンを用いて構成した監視用端末装置９、診断サーバー１０およびメールサーバー１３を接続してＬＡＮ（構内情報通信網）１１が構成される。監視用端末装置９は、メールソフト又はメーラーを使用してダイアルアップルータ１２、公衆通信回線８を介して遠隔地に配置された各設備監視装置１とメールの送受信を行う。   A management center 14 is arranged at a remote location appropriately separated from each facility monitoring device 1. The management center 14 is connected to a data transmission line connected to the public communication line 8 via the dial-up router 12, for example, by connecting a monitoring terminal device 9, a diagnostic server 10 and a mail server 13 configured using a personal computer. (Local information communication network) 11 is configured. The monitoring terminal device 9 transmits / receives mail to / from each facility monitoring device 1 disposed at a remote location via the dial-up router 12 and the public communication line 8 using mail software or a mailer.

図３に、設備監視装置1が外部から、例えば、監視用端末装置９から受信したメールデータの一例を示す。このメールデータは調査用メールデータの一例であり、空気調和機の故障原因の調査用プログラム２０１と、調査の緊急度２０２ａ、対象機器２０２ｂ等の故障診断プログラムの実行条件を示すデータを含む。   FIG. 3 shows an example of mail data received by the equipment monitoring apparatus 1 from the outside, for example, from the monitoring terminal apparatus 9. This mail data is an example of investigation mail data, and includes data indicating the execution conditions of the investigation program 201 for the cause of failure of the air conditioner and the failure diagnosis program such as the investigation urgency level 202a and the target device 202b.

次に、実施の形態１の空気調和機の故障診断システムの動作について説明する。
空気調和機に故障が発生した場合、故障した空気調和機からその故障事象を示す情報、例えば、故障コードデータが設備監視装置1の送受信部２６に送られ、設備監視装置１のメール送信部２３から監視用端末装置９宛に故障コードデータを含むメールデータが公衆通信回線８を介して送られ、該メールデータを受信した監視用端末装置９は空気調和機に故障が発生したことを検知する。 Next, the operation of the air conditioner failure diagnosis system according to Embodiment 1 will be described.
When a failure occurs in the air conditioner, information indicating the failure event, for example, failure code data is sent from the failed air conditioner to the transmission / reception unit 26 of the equipment monitoring device 1 and the mail transmission unit 23 of the equipment monitoring device 1. Is sent to the monitoring terminal device 9 via the public communication line 8 and the monitoring terminal device 9 that has received the mail data detects that a failure has occurred in the air conditioner. .

監視用端末装置９は、受信したメールデータに含まれる空気調和機の故障状態を示す情報から、該空気調和機における冷媒系の圧力および温度、空気系の温度および湿度を検出する各種センサ、圧縮機、送風機、弁などのアクチュエータ等、空気調和機を構成する各部位が故障していないかを調査するため、各部位を調査するために予め診断サーバー１０に格納されたデータベースから適切な調査用故障診断プログラムを選定する。   The monitoring terminal device 9 includes various sensors for detecting the pressure and temperature of the refrigerant system and the temperature and humidity of the air system in the air conditioner from the information indicating the failure state of the air conditioner included in the received mail data, compression In order to investigate whether each part that constitutes the air conditioner, such as an actuator such as a fan, a blower, or a valve, has failed, it is suitable for investigation from a database stored in the diagnostic server 10 in advance in order to investigate each part. Select a fault diagnosis program.

故障診断プログラムの選定は、過去の故障履歴、修理履歴、収集した空気調和機の運転状態等の保存データに基づいて予め決められたルールに従って行われる。なお、故障率の高い部位を所定の手順で故障診断する検査プログラムを実行して選定することができる。また、調査状況に合わせて、適宜調査用の故障診断プログラムを選定することができる。   The selection of the failure diagnosis program is performed according to a rule determined in advance based on stored data such as past failure histories, repair histories, collected air conditioner operating conditions, and the like. It is possible to select by executing an inspection program for diagnosing a part having a high failure rate according to a predetermined procedure. Further, a failure diagnosis program for investigation can be selected as appropriate according to the investigation situation.

監視用端末装置９は、上述したように選定した故障診断プログラムを含む、例えば図３に示すメールデータを生成し、メールサーバー１３から公衆通信回８を介して調査対象の空気調和機を監視する設備監視装置1宛にメールデータを送信する。このメールデータは、設備監視装置１のメール受信部２４で受信される。 The monitoring terminal device 9 generates, for example, the mail data shown in FIG. 3 including the failure diagnosis program selected as described above, and monitors the air conditioner to be investigated from the mail server 13 via the public communication times 8. The mail data is sent to the equipment monitoring device 1. This mail data is received by the mail receiving unit 24 of the equipment monitoring apparatus 1.

設備監視装置1のＣＰＵ２８は、メールデータ受信部２４で受信したメールデータを一旦、故障診断プログラム格納部６に格納する。次に、ＣＰＵ２８はメールデータに含まれる故障診断プログラムを実行するための実行条件を確認する。この確認処理において、予め定められたプログラム実行条件を全て満たした場合にのみ、プログラム実行手段により空気調和機に対する通常の運転制御及び監視用の制御監視プログラムに優先して故障診断プログラムを実行する。   The CPU 28 of the equipment monitoring apparatus 1 temporarily stores the mail data received by the mail data receiving unit 24 in the failure diagnosis program storage unit 6. Next, the CPU 28 checks the execution conditions for executing the failure diagnosis program included in the mail data. In this confirmation process, only when all predetermined program execution conditions are satisfied, the failure diagnosis program is executed by the program execution means in preference to the normal operation control and monitoring control monitoring program for the air conditioner.

設備監視装置1は、故障診断プログラムを実行することにより得られた故障診断結果及び空気調和機の運転状態を示す情報を含むメールデータを生成し、メール送信部２３からメールソフトに予め登録された送信先の管理センター１４内の監視用端末装置９に送信される。なお、設備監視装置１からのメールデータの送信先は、管理センター１４内の監視用端末装置９に限らず、携帯電話機、ＰＤＡ（Personal Digital Assistantで個人向け携帯型情報機器）、保守業者のパーソナルコンピュータであってもよい。   The equipment monitoring device 1 generates mail data including information indicating the failure diagnosis result obtained by executing the failure diagnosis program and the operating state of the air conditioner, and is registered in advance in the mail software from the mail transmission unit 23. It is transmitted to the monitoring terminal device 9 in the management center 14 of the transmission destination. The transmission destination of the mail data from the facility monitoring device 1 is not limited to the monitoring terminal device 9 in the management center 14, but is a mobile phone, a PDA (Personal Digital Assistant for personal portable information equipment), a personal service provider. It may be a computer.

実施の形態１の故障診断システムにおいては、上述したように、監視用端末装置９は、設備監視装置１から送信されたメールデータにより空気調和機の故障発生を検知した際、該設備監視装置１が空気調和機の故障原因を調査するための故障診断プログラムをメールデータとして取得するようにしたから安全かつ容易に故障診断することができる。   In the failure diagnosis system of the first embodiment, as described above, when the monitoring terminal device 9 detects the occurrence of a failure of the air conditioner from the mail data transmitted from the facility monitoring device 1, the facility monitoring device 1 However, since the failure diagnosis program for investigating the cause of the failure of the air conditioner is acquired as mail data, the failure diagnosis can be performed safely and easily.

また、調査の状況により、必要な故障診断プログラムだけを選別し、実行するようにしたので、膨大なプログラムを記憶する必要がなく、迅速かつ的確に故障診断することができる。   Further, since only necessary failure diagnosis programs are selected and executed according to the state of investigation, it is not necessary to store an enormous number of programs, and failure diagnosis can be performed quickly and accurately.

さらに、膨大なプログラムを予め実装する必要がなく、製作コストが安価なものとすることができる。
実施の形態２． Furthermore, it is not necessary to mount a huge program in advance, and the production cost can be reduced.
Embodiment 2. FIG.

この実施の形態２の空気調和機の故障診断システムに適用される設備監視装置１は、図４に示すように、上述した実施の形態１におけるものと比べ、メールデータとして受信した故障診断プログラムをそのまま実行するＣＰＵ２８に代え、空気調和機の運転制御し、運転状態を収集する通信コマンドにより故障診断プログラムによるものと等価の故障診断処理をするＣＰＵ４１を備える点が相違し、その他の構成部分は実施の形態１におけるものと同様である。   As shown in FIG. 4, the facility monitoring apparatus 1 applied to the air conditioner failure diagnosis system according to the second embodiment has a failure diagnosis program received as mail data, as compared with the first embodiment described above. Instead of the CPU 28 that is executed as it is, it is different in that it includes a CPU 41 that controls the operation of the air conditioner and performs a fault diagnosis process equivalent to that by the fault diagnosis program using a communication command that collects the operating state. This is the same as in the first embodiment.

図４に示す実施形態２の故障診断システムに適用できる設備監視装置１のＣＰＵ４１は、空気調和機の運転制御や運転状態の監視を行う監視制御回路４２、調査の状況にあわせて送信条件などの通信コマンドの設定条件を変更する設定変更回路４３、該設定変更回路４３により変更された設定条件を反映し、空気調和機の運転制御や運転状態を示す情報を収集するための通信コマンドを生成するコマンド生成回路４４、故障診断プログラムなどを実行するプログラム実行回路４５、室内機などに接続されている手元リモコン(図示せず)の操作の禁止及び許可を指示する操作制限回路４６および故障診断プログラムを実行するかどうかを指本する実行指示回路４７により構成されている。   The CPU 41 of the equipment monitoring apparatus 1 that can be applied to the failure diagnosis system of the second embodiment shown in FIG. 4 includes a monitoring control circuit 42 that controls the operation of the air conditioner and the monitoring of the operating state, transmission conditions, etc. A setting change circuit 43 for changing the setting condition of the communication command, and a communication command for collecting the information indicating the operation control and the operating state of the air conditioner are generated by reflecting the setting condition changed by the setting changing circuit 43. A command generation circuit 44, a program execution circuit 45 for executing a failure diagnosis program, an operation restriction circuit 46 for instructing prohibition and permission of an operation of a local remote controller (not shown) connected to the indoor unit and the like, and a failure diagnosis program The execution instruction circuit 47 is configured to specify whether or not to execute.

この実施の形態２の故障診断システムにおいては、実施の形態1のもの同様、空気調和機の故障を示す情報に基づき、設備監視装置１は、図1に示す監視用端末装置９からメールデータとして送信された故障診断コマンドをメール受信部２４で受信する。設備監視装置１の操作者は、故障原因の調査状況や緊急度などによって、空気調和機に送信する通信コマンドに対し、設定変更回路４３により必要に応じて設定内容の変更を行う。また、故障診断を行う場合、特定の手順に従って通信コマンドを空気調和機に送信し、空気調和機の運転制御および運転状態を示す情報を収集するにあたり、監視対象の空気調和機のユーザーにより、図示しない手元リモートコントローラ（以下、リモコンと略称する）が操作されて現在の運転状態が変更されることのないように、操作制限回路４６により、診断対象の空気調和機に接続された手元リモコンの操作を禁止する。故障診断の終了後、手元リモコンの操作禁止を解除して操作許可状態に復帰させる。   In the failure diagnosis system according to the second embodiment, as in the first embodiment, the facility monitoring device 1 receives mail data from the monitoring terminal device 9 shown in FIG. 1 based on information indicating a failure of the air conditioner. The transmitted failure diagnosis command is received by the mail receiving unit 24. The operator of the equipment monitoring apparatus 1 changes the setting contents as required by the setting change circuit 43 for the communication command transmitted to the air conditioner according to the investigation status of the cause of failure or the urgency level. When performing failure diagnosis, a communication command is transmitted to the air conditioner according to a specific procedure, and when collecting information indicating the operation control and operation state of the air conditioner, the user of the monitored air conditioner The operation restriction circuit 46 operates the local remote controller connected to the air conditioner to be diagnosed so that the current operating state is not changed by operating the local remote controller (hereinafter abbreviated as a remote controller). Is prohibited. After the failure diagnosis is completed, the operation prohibition of the local remote controller is canceled and the operation is permitted.

設備監視装置1は、通常、空気調和機の運転制御や運転状態の監視を実行し、空気調和機の運転状態が予め定めた運転条件を満足したと判定したとき、実行指令回路４７により故障診断を開始する。故障診断の開始条件は、空気調和機のユーザーによる利用状況、故障の調査状況等に基づいて判定される。   The equipment monitoring apparatus 1 normally performs operation control of the air conditioner and monitoring of the operation state, and when it is determined that the operation state of the air conditioner satisfies a predetermined operation condition, a failure diagnosis is performed by the execution command circuit 47. To start. The failure diagnosis start condition is determined based on the usage status of the air conditioner by the user, the status of the failure investigation, and the like.

上述したように、実施の形態２の故障診断システムにおいては、故障の調査状況に応じて通信コマンドの設定を変更するようにしたので、精細な故障状態調査を行うことができ、低コストで正確な故障診断システムを得ることができる。
実施の形態３． As described above, in the failure diagnosis system according to the second embodiment, the setting of the communication command is changed according to the failure investigation status, so that a detailed failure state investigation can be performed, and the cost can be accurately reduced. A fault diagnosis system can be obtained.

In addition, failure diagnosis programs assigned to a predetermined time schedule are sequentially executed. In the time schedule table 51 of FIG. 5, the failure diagnosis program execution day is displayed in the left column, the execution time of the failure diagnosis program is displayed in the middle column, and the identification name of the failure diagnosis program is displayed in the right column.

実施の形態３の空気調和機の故障診断システムにおいては、図５のタイムスケジュール５１に示されるように、タイマ回路を介して故障診断プログラムを割り付けておくことで、空気調和機が故障を発生する以前から、空気調和機に含まれる種々のセンサ、アクチュエータ等に故障が発生していないかどうかを診断することができる。これにより、機器の劣化や故障を未然に予測し、空気調和機の保守を計画的に行うことが可能である。   In the air conditioner failure diagnosis system according to the third embodiment, as shown in the time schedule 51 of FIG. 5, the air conditioner generates a failure by assigning a failure diagnosis program via a timer circuit. It is possible to diagnose whether or not a failure has occurred in various sensors and actuators included in the air conditioner. As a result, it is possible to predict the deterioration and failure of the device in advance and to perform maintenance of the air conditioner systematically.
